IMPROVEMENT IN COOKING-STOVES.

Specication forming part of Letters Patent No. 119,045, dated September 19, 1871.

lTo all 'whom it may concern:

Be it known that I, DANIEL ELDoN PARIS, of the city of Troy, county of Rensselaer, and State of New York, have invented new and useful improvements 1n a flue-chamber for water-reservoirs for cooking-stoves and ranges, together with the manner of attaching them'to the stove or range; and I do hereby declare that the fol- 'lowing is a full, clear, and accurate description Of my said improvements, reference being had to the accompanying drawing and letters marked thereon, like letters representing like parts.

Figure 1 is a perspective View of the rear part of a divingilue cooking-stove, showing the reservoirL made in two parts, and the outer side wall of the flue-chamber N, the outer'wall itself beinglettered A. Fig. 2 is' a vertical section Vtaken through the center of the stove, liront to rear, showing the connection of the parts and their relations to each other. Fig. 3 is a horizontal section taken through the due-chamber N, .the reservoir being removed. Fig. 4 is a perspective rear view of the liuc-chamber N, the reservoir being removed. Figs. 5 and 6 are modifications merely of the invention, showing the same arrangement of lues, but giving different positions to the reservoir, Snc. Fig. 6 shows the reservoir raised up to a level, or nearly so, with the stovetop B. It is the same in all other respects as Fig. 2. Fig. 5 shows the reservoir in a lower position than either Fig. 2 or Fig. 6, and with the outer wall A of .the chamber N- carried up to or near the level of the stove-top B, and the reservoir sitting inside of the same. When thus made the reservoir may still be in one or two parts 5 but, if made in two parts, there should be a bar or central support for them running from the rear part of the stove-top B immediate 1y in rear of the pipevcollar, and between the two, to the central rear part of the casing A at B. By the direction of the arrows in Figs. 3 and 4it will be seen that the products of combustion pass r'st into the side ilues Q Q and thence into the central flue P, coming in contact with the reservoir and all these flues, for the purpose only of heating it; it will be seen also when the reservoir is below the top B, or far below it,"that this heat is made to pass down the two side ilues Q Q below the horizontal plane of the top ovenplate, and thence, and thereafter, into the central ilue I); and this heat is shut off or turned on by means of the damper O 5 but the damper O may have many equivalents; there may be, for instance, a similar damper in each of the side flues Q Q instead of one in the central flue only, and thus the effect would be the same. B-y this arrangement of lues the products of combustion are made to operate directly and powerfully upon the. reservoir before they enter the eXitopening at T, and without going around the oven or materially effectingit. Figs. 2 and3 show the top and rear ilues of the stove, together with the flues in the seat below .the reservoir, the damper O and the seat N; show also that the heat, as it passes from the fire-box, goes down the two side ilues of the stove, and then (when the damper O is open) it passes into the chamber below the reservoir, and thus turning inward in the direction of the arrows it passes into the central rear flue of the stove and thence upward into the smokepipe. This motion ofthe heat or products of combustion is seen again from the direction of the arrows in Fig. 4; but if the damper O be closed the heat of the lines-that is, the products of combustion-does not come into active contact with the reservoir, but passes around the oven in the usual way, just as though no reservoir were attached to the stove. By opening the damper O the heat is not forced through the seat N, but

simply allowed or let to pass through it, which^"` it will always do, for it will, of its own motion, take the shortest passage to the smoke-pipe, but if the damper O be closed, the heat is forced to go around the oven as it can go in no other direction.

In the arrangement of iiues in the seat N, I

have secured a most valuable improvement in back-reservoir stoves. The stove to which I have attached this improvement is a common three-flue stove; the main object sought here, and also in my application iled January 20, 1869, is to heat the reservoir by a quick direct draught from the re-boX, by which the products of combustion are thrown into direct contact with the bottom of the reservoir without going'rst around the oven, as in the Spaulding patent. In my application of January 20 I secured this object in a two-ilue stove; here I secure it in a three-line stove. Another feature is secured here, viz., the simpliiication of the invention. I need use but one back damper-and one damper, at least, is required in any common plain-top stoveand thus all persons who know anything of a cooking-stove know how to operate it. rlhe damper O in the seat N is the only one I need have with this arrangement of iiues; another may be made, if desired, in the usual place infront of the pipecollar. Vhen the damper O is open the draught is sufficiently direct for all practical purposes, the heat or smoke making only a slight detour downward through the chamber N; and even this may be made still more slight by raisin g thereservoir half or wholly its height above the stovetop, as seen in FiO. 6, and, by thus raising the chamber N, plenty of room is had below for the usual warming-oven, thus improving the stove. I prefer a middle position for the reservoir and seat, as shown in Figs. l and 2, which is better, all things considered, and especially when a closet is used, which is always desirable. It is not necessary that the reservoir be divided into two parts, for it may bemade in one part only and occupy the same position above described. By this position for the reservoir I get room for a large warming-closet lbelow it, which cannot bel had where the reservoir is level with the stove top. In this construction the reservoir need not be made removable from the stove, but be mounted into the stove and form of itself the covering to the chamber N. I have shown this back reservoir with three lues under it, the two side iiues Q Q and the central flue l?, (see Figs. 3 and 4;) but the same principle will work equally we ll with only two iiues. 'lake, for instance, one of the side ilues Q away, and then move the remaining iiue-strip C to the center of the stove, and you still have the same motion of heat as previously described, viz., a downward and upward draught through the flue-seat N.

What I claim as new in this back reservoir is not the position of the reservoir behind the stove, nor a seat, nor a {ine-chamber simply under a reservoir, for Mr. Stewart and Mr. Spaulding have anticipated me in the matter of a flue-space formed underneath a reservoir for the purpose of heating it, and Hydes application of 1858 combines a reservoir with the back of the stove; so that, in these general particulars, Iclaim nothing new; but I claim as entirely new my arrangement of ilues. In the Spaulding patent the bottoln ue or flues of the stove were extended under the reservoir for the purpose of heating it, and in my improvelnents 011 that patent, which were granted me July 80. and August 13, 1867, I followed closely Spauldings idea of extending the bottom flue or iiues of the stove under the reservoir, although I turned the flue slightly upward into an improved flue-chamber 5 butthe general result was the same as in the Spaulding patent, and the heat was driven and forced under the reservoir by a damper, after it had irst operated 011 the oven, being used then and thereafter on the reservoir; while in the Spaulding patent, therefore, and in my improved patents, the reservoir was heated by practically or in ei'- fect extending the bottom flues. In this invention I heat the reservoir by practically or in eect extending the top iiues ofthe stove, for the heat passes over the top of the oven, thence luider the reservoir, and thence upward into the exit-pipe. In those patents the damper compelled the heat to go under the reservoir out of its direct course; in this, the damper simply permits the heat to go under the reservoir in its direct course. In those patents the heat or products of combustion operated directly upon both the oven and reservoir before entering the exit-pipe; in this, that result is impossible. The material point of value in this back reservoir, and, in this respect, wholly unlike any other7 is the absolute independence of the reservoir and the oven-only one can be actively heated at atime. Thereservoiris no detriment to the oven, nor the oven to the reservoir. The oven heats no slower because of the reservoir, nor the reservoir any slower because ofthe oven, and each heat in the quickest manner possible; or the heat is turned away from either at pleasure, and, besides, only one damper is needed to produce these results. The seat or chamber N may be brought up to a level with the stove-top, as seen in Fig. 6, for its depression downward is no part of my present invention; and when brought up to the stove top it would resemble somewhat the invention of I). P. Stewart, but would be unlike that except in the mere fact of a liuc-seat below the reservoir, which I do not claim. In an ordinary stove the tlues extend under the oven, forward from and then backward to the exit-pipe T; in this stove the iiues not only perform this oiiice, but they also extend backward from and then forward to the exit-pipe T, for the purpose of heating the reservoir; and the movement or operation of each is entirely different and for a different purpose. In place of a close plate at S, there may be, if preferred, a damper, as seen in Fig. 2. The only advantage gained would be the doubtful one of having a direct draught that would heat neither the oven nor the reservoir. This damper is the usual threeiiue damper covering the front of the central iiue.

Having thus explained the nature of my said improvements, I claim as newl. The two side rear lues Q Q to a diving-flue cooking-stove, so arranged as to connect with the rear central iiue I by means of a damper or dampers, and so that the products of combustion, after passing into the side lues Q Q, shall immediately thereafter (when said damper or dampers are open) pass into the rear central iiue P for the purpose of heating, and in combination with a water-tank or reservoir situated in rear of said iiues, substantially as herein shown and described.

2. The extension of the top iiues of a divingiiue cooking-stove beyond the rear vertical line of the exit-pipe, and underneath a reservoir or reservoirs, and thenceback toward and into said exit-pipe, substantially in the manner and for the purpose herein shown and described.

3. A downward and upward-draught smokeiiue or iues at the rear end of the stove, connected into and in combination with a iiue-chamber below the reservoir, and so arranged that the products of combustion shall pass irom the top ilue of the stove down one or more of said ues into and through said chamber and thence upward to the exit-pipe7 for the purpose and substantially in the manner herein shown and described.

4. The damper O, or its equivalent, made to operate as follows: When open7 to let the heat or smoke pass into the central Hue P to heat the reservoir, and, When closed7 to drive it around the oven of the stove7 substantially as herein shown and set forth.

5. For a diving-flue cooking-stove or range, one or more double-acting1 ilues7 made to pass each Way from the exitpipe7 and controlled by a damper, arranged, When passing in rear of said pipe, to heat the reservoir, When in front of it, to heat the oyen7 substantially in the manner herein shown and described.
